Chatclient
Chatclient is a custom AI agent builder for businesses that want ChatGPT-style chat on their own website. You upload documents, paste text, or point it at your site, and it trains an agent that answers questions from that content. The result is an embeddable chat widget or API you can drop into any page.
The platform targets customer support, lead generation, and user engagement. Agents can collect leads, hand off to human support when answers fall short, and run across 95+ languages even when your source data is in one language. Integrations cover Slack, WhatsApp, Zapier, and more, with auto-retrain options to keep agents synced with your latest content.
Model choice spans fast and advanced tiers depending on plan, including GPT-4o Mini, Claude 3.5 Haiku, Gemini 1.5 Flash, GPT-4o, Claude 3.5 Sonnet, Claude 3 Opus, and Gemini 1.5 Pro. Whitelabel and custom domain options are available for teams that want to remove Chatclient branding.

Human escalation on the Pro plan gives customers a path to real support when AI answers are not enough.
Yearly billing includes two months free, which lowers cost for teams committing long term.
Free tier lets you test with real message credits before paying for higher limits.
The free plan caps training at 500 links and 500,000 characters per agent, which limits larger knowledge bases.
Advanced models and integrations only unlock on paid tiers, so serious deployments require a subscription.
Pricing is credit-based, so heavy chat volume can push you toward higher plans quickly.
Whitelabel and custom domain options are sold separately via email rather than self-serve checkout.
